中文摘要：

BN-SiO ₂-SiAlON 合成陶艺被热压的 sintering 的工具成功地准备。霍尔推进器产生的 Xe 血浆流动被用于劈啪作响样品的表面以便评估血浆侵蚀抵抗。XRD， TEM， SEM，和 LSCM 被用来在 Xe 血浆侵蚀前后描绘阶段作文和同样做的合成陶艺的形态学。陶艺由 h-BN，熔化硅石，和 SiAlON 组成，它在 Xe 血浆劈啪作响的过程期间维持了结构的稳定性。在结论，把合成陶艺与 BN-SiO ₂ 作比较， BN-SiO ₂-SiAlON 的血浆侵蚀率合成陶艺然后起初显著地减少有 AlN 增加的增加的上升。侵蚀坑能被在血浆劈啪作响以后在表面上使用 SEM 观察，它证明 BN 谷物减少了表面。另外，由高速度的 Xe 离子的机械剥光为 BN 矩阵合成材料作为损害机制被认出。

英文摘要：

BN-SiO_2-SiAlON composite ceramics were successfully prepared by the means of hot pressed sintering.Xe plasma flow generated by HallThruster was used for sputtering the surface of the samples in order to evaluate the plasma erosion resistance.XRD,TEM,SEM,and LSCM were used to characterize the phase composition and morphologies of as-made composite ceramics before and after Xe plasma erosion.The ceramics were composed of h-BN,fused silica,and SiAlON,which maintained structuralstability during the process of Xe plasma sputtering.In conclusion,comparing with BN-SiO_2 composite ceramics,the plasma erosion rate of BN-SiO_2-SiAlON composite ceramics decreases significantly at first then rises with the increase of AlN addition.Erosion pits can be observed by using SEM on the surface after plasma sputtering,which demonstrates that the BN grains have dropped off the surface.In addition,mechanicaldenudation by high-speed Xe ions is recognized as the injury mechanism for the BN-matrix composite materials.
